tain new and useful Improvements in ()il- Heaters, of which the following is a specilicahad therein to the accomp anying drawing.

:This invention relates to certain new and useful improvements in oil heaters, and the primary object of the invention is to provide an oil heater having a plurality of lamps, each of which may be used independently, or coniointly with the remaining lamps, so that a greater or lesser amount of heat can be had as desired.

Another object of the present invention is to provide an oil heater having a plurality of radiating tubes whereby a greater amount of radiating surface is obtained, and whereby the heat is brought in closer contact with such radiating surface.

A still further object of the invention is to provide an oil heater with means whereby the air may be kept moist and wholesome, and the fumes of combustion arising from the heater dissipated to a very considerable extent. v

The construction by which the above and other objects are'obtained will be hereinafter specifically described and then particularly pointed out in the claims, and in describing the invention in detail, reference will be had to the accompanying drawings forming a part of this application and illustrating a practical embodiment of my invention. 7

In these drawings: Figure 1 is a side elevation of an oil heater constructed in ac cordance with my invention; Fig. 2 is a view of the same partly in side elevation and partly in vertical section; Fig. 3 is a horizontal sectional view taken on the line ;ra' of Fig. 1; Fig. 4 is a horizontal sectional view taken on the line 111-212 of Fig. 1 Fig. 5 is a sectional view showing a modi'lied form of construction of heater top.

In the practice of my invention, 1 use a plurality or multiple number of smaller lamps, instead of one large lamp as is the common practice in heaters of this type. The lamps used by me are each of that type known in the artas center dra'lt burners, that is, lamps which have a cylindrical wick, and a corresponding cylindrical opening extending vertically from the top to the bottom of the lamp. As this type of lamp is well known in the art, and in the trade, 1 have not shown the interior construction ol the lamp in detail, as same will be readily understood.

As stated above, I employ a plurality ol lamps l, oi the type stated having a central dral't opening (1, shown in dotted lines in one of the lamps in Fig. 1. These lamps are mounted on a hollow base or base-drum 2, provided with air inlet openings 3 in its side wall, or otherwise Constructed so that air can freely enter from the exterior of the drum to the centralopening oi the lamps. Mounted on this base or base-drum '2, is a plurality of stai'idards or uprights -i, which at their upper ends support a drum This upper drum is open at its top, and has the bottom thereof provided with as many openings as there are lamps utilized in the burner. These openings in. the bottom of said upper drum receive the upper ends of the heat radiating tubes, the lower ends of which tubes are titted in the burners oi the lamps, the said tubes thus constituting chimneys for the lamps l. The said radiating tubes are prelerably constructed in sections. the upper section 6 entering the bottom of the drum 5, and the lower section 7 of the tube telescoping on the section 6, and having a neck or sleeve portion 8 on its lower end adapted to ilit neatly with the burner oi" the lamps l A small handle 9, is provided for raising and lowering the telescoping section 7 of the tube, which handle may be carried by the sleeve 8, or located at any other desired pointon the movable section of the tube, and is preferably provided with a knob oi nonconducting material, which will not be at- -fected by the heat.

The upper section (5 of the radiating tubes may be extended upwardly within the upper drum above the bottom ol" the latter, and iitted neatly with the openings provided therefor in the bottom of said drum, whereby to permit the utilization olthe upper drum as a water pan to keep the heated air in the moist condition. in lieu of utilizing the upper drum as the water pan however, I may employ a separate pan 1 U, the bottom olwhich has openings registering with the openings in the bottom of the upper drum 5, and consequently registering with the radiating tubes, and this pan carries vertical tubes 11, which register with the radiating tubes. 1t willbe evident that where the water pan 10 is employed, the upper section 6 of the radiating tubes may, if desired, be extended only through the bottom of the upper drum 5.

Supported above the upper drum is a heater cover, which in Figs. 1 and 2 of the drawings is shown in the form of a drum-like structure 12, the lower edge of which is secured to a band 14, of somewhat larger diameter than the diameter of the upper drum 5, whereby an outlet space 15 is provided between the band 14 and the drum 5, thesaid band being so positioned with respect to the drum that its lower edge is a slight distance below the upper edge of the drum, whereby to cause the heated air to be deflected downwaroly from the cover 12. This cover may be supported in any suitable manner as by legs 16 attached thereto at their upper ends and having theirlower ends resting on the bottom of the drum 5 as clearly illustrated in Fig. 2 of the drawings, thus permitting the ready removal and replacing of the cover at any time desired.

In Fig. 5 of the drawings I show a modification of the cover, in which the band 14: is provided with a flat top 17, in lieu of the dome-like top 12 shown in Figs. 1 and 2. This flat top is advantageous where it is desired to use the stove for cooking purposes. It will be evident that while I have shown and described two forms of top, that other forms of top can be readily used in connection with the construction of stove desired, and I do not therefore wish to be understood as limiting myself to the construction of stove described in connection with a particular construction of top therefor.

he construction of the heater will, it is thought, be clearly apparent from the foregoing description taken in connection with the accompanying drawings, though I desire to call attention to advantages gained by this construction, namely, that by utilization of a closed base admitting air only through the center of the lamp, the air is heated thoroughly, and a good circulation of the air is obtained. The utilization of a plurality or multiple number of smaller radiating tubes instead of one large tube gives a considerably greater amount of radiating surface, and brings the heat in closer contact with such surface than if the same amount of radiating surface were provided for one lamp. Furthermore, the utilization of a multiple number of lamps, permits of the use of one or two or more lamps at one time, so that the quantity of heat can be regulated as desired. The radiating tubes extending into a water pan, whether the latter be a separate pan placed in the drum 5, or the drum 5 itself utilized as the water pan, serves to keep the heated air moist and wholesome, as the heated air ris l I l l l l r l I 1 l ing against the hood or cover is deflected and mixed with the vapor from the water, serving to take up practically all the fumes of combustion given off from the fuel.

Various slight changes may be made in the details of construction as may be included within the spirit of the invention and as deiined in the following claims:

Having fully described my invention, what I claim is:

-1. In an oil heater, a base, a plurality of lamps supported on said base, each having a burner, a plurality of heat radiating tubes, one for each lamp, each radiating tube com- 1 prising an upper stationary section a lower movable section telescoping the stationary section, and a sleeve carried by the lower section to fit neatly with the burner of the lamp, a plurality of standards mounted on said base, a drum or water upper end of said standards and into which the upper ends of the stationary sections of the heat radiating tubes are received and neatly fitted, and a top removably supported from said lying below the upper edge of said drum.

2. In an oil heater, a base, a plurality of lamps mounted on said base, each havinga burner, a plurality of heat radiating tubes, one for each lamp, each tube comprising an upper stationary section, a lower section teleseo in the u er section and a sleeve car ried by the lower section to fit neatly with the lamp burner, a stationary drum constituting a water pan fitted over the upper ends of the upper sections of the heat radiating tubes and with which said sections are connected, and a top removably-supported from the drum or water pan having its lower edge of greater diameter than the drum whereby to form an air space between the periphery of the drum and said top.

3. In an oil heater, a supporting base, a plurality of lamps mounted thereon, each having a burner, a heat-radiating tube for each lamp, a plurality of standards mounted on said base, a drum constituting a water pan mounted on the upper ends of said standards and into which the upper ends of said heat radiating tubes are received, and a top or cover comprising a ring of larger diameter than the drum and disposed with its lower edge slightly below the upper end of said drum, a cover carried by said ring, and supporting legs attached to the cover proper and resting on the drum.
